P CHEVROLET Cavalier Coupe

Fixing the head gasket on a 2.2 OHV Chevrolet Cavalier involves a detailed process requiring mechanical skill and several steps. Here is a general overview:

Step-by-Step Process to Replace the Head Gasket on a 2.2 OHV Chevrolet Cavalier:

1. Preparation:
- Disconnect the battery.
- Drain the coolant from the radiator.
- Remove air intake components and any parts blocking access to the cylinder head (such as alternator, belts, and hoses).

2. Remove the Cylinder Head:
- Unbolt the cylinder head bolts following the correct sequence.
- Carefully lift the cylinder head off the engine block.
- Inspect the cylinder head and engine block for warping or cracks; use a straightedge and feeler gauge.
- If warped, the head will need to be machined (resurfaced) to ensure a flat sealing surface.

3. Clean and Inspect:
- Clean the cylinder head and engine block surfaces thoroughly.
- Check for damage or cracks.
- Inspect and possibly replace valve cover gaskets, intake and exhaust gaskets.

4. Install New Head Gasket:
- Place the new head gasket carefully on the engine block, ensuring correct orientation.
- Replace all head bolts with new ones (old bolts can stretch and fail).
- Torque the bolts to specification in the proper sequence using a torque wrench.

5. Reinstall the Cylinder Head and Components:
- Refit the cylinder head.
- Reassemble all removed parts in reverse order.
- Refill coolant and oil.

6. Final Steps:
- Prime the cooling system and check for leaks.
- Start the engine and check for proper operation.
- Monitor engine temperature and oil/coolant levels over the next few days.

Tips:
- Use a quality head gasket and related seals.
- Double-check all torque specs and bolt sequences.
- Consider replacing the timing belt and water pump if applicable.
- Keep all removed parts organized.
- Allow sufficient time for the repair; it's labor-intensive and requires patience.
- If unsure about warping or machining, consult a professional machine shop.

Resources:
- Detailed DIY videos exist showing head gasket replacement on similar 2.2L Chevy engines.
- Many DIYers recommend thorough head and block inspection to avoid repeated failure.

In summary, replacing the head gasket on a 2.2 OHV Chevy Cavalier requires careful disassembly, inspection, cleaning, gasket placement, and reassembly with precise torqueing. Properly checking for head warping and damage is critical to success.
